Too much vitamin B

Vitamin B is a group of vitamins that are water-soluble. The most prevalent function of vitamin B group is to assist in healthy cell metabolism.

The reason for vitamin B to be divided in the group of numbers is due to the initial classification of vitamin B as a single chemical composition. Subsequent research has shown that the elements of this group are substantially chemically different while the presence of each element could be found in the same food source.

The entire group of 8 vitamins is essential for breakdown of carbohydrates into glucose, processing of fats along with proteins, support of muscle functions, gastrointestinal tract, liver function, skin health, hair, eyes health and mucous membranes of the mouth.

The vitamin B complex consists of

B1 – Thiamine – breakdown of carbohydrates into glucoseB2 – Riboflavin – processing of fats and proteinsB3 – Niacin – responsible for metabolic transfer of fat, alcohol and glucose with help of nicotinic acid and nicotinamideB5 – Pantothenic acid – oxidation of carbohydrates and fatty acidsB6 – Pyridoxine – metabolism of lipids and amino acids, production of hemoglobin and neurotransmitters as well as nicotinic acid (a.k.a B3)B7 – Biotin – metabolic conversion of proteins, carbohydrates and lipidsB9 – Folic acid – transfer of single carbon in the metabolic function of cholesterol, amino and nucleic acids B12 – Cobalamin – facilitates healthy production of blood cells within bone marrow, proteins and nerve pathways while being involved in conversion of lipids, proteins and carbohydrates.

Too much vitamin B intake can become toxic

Vitamin B group is water-soluble and is considered to be a low toxicity compound due to a rapid excretion through urine. However, some toxicity can occur and cause an array of conditions that usually resolve with discontinuation of vitamin B intake. Vitamin B group is also a potential hazard to liver health since it is stored in the liver.

The modern tendencies found in many vitamin B supplements can eventually disrupt many body function mechanisms if taken on a long term. Unless an individual is low in specific vitamin B compounds and confirmed via blood tests, it is strongly suggested to intake all vitamin Bs from foods and not from supplements.

Known side effects, conditions and dangers when too much of vitamin B elements concentration present in the body

Vitamin B1 – no clinically documented thiamine side effects from oral intake, although there are reports of anaphylaxis through intravenous injections of thiamine

Vitamin B2 – partial studies on animals and humans report no evident riboflavin toxicity, although free radicals are shown to be formed in vitro studies under significant exposure of riboflavin to ultraviolet light spectrum

Vitamin B6 – excessive pyridoxine intake is associated with peripheral neuropathy and skin lesions. May cause excessive urination as a diuretic and insomnia as it releases glucose stored in muscles and converts amino acids (blocks of proteins) into glucose, raising blood sugar. Causes insomnia and provokes a hyperthyroid condition in some individuals.

Vitamin B7 – no well pronounced biotin toxicity is known

Vitamin B9 – folic acid may mask existing B12 deficiency, thus leading to permanent neurological damage. Symptoms of vitamin B12 deficiency are rapid heartbeat and breathing, fatigue, weakness, pale skin, sore tongue, easy bruising and bleeding of the gums, constipation or diarrhea. Vitamin B12deficiency can also result in nerve cell damage that presents with symptoms of tingling or numbness in fingers and toes, difficulty walking, depression, memory problems and dementia

The approach to detoxify from vitamin B overdose is to immediately stop any vitamin B supplementation. It is strongly recommended that the best way to get appropriate amounts of B group of vitamins is through the foods and not supplements. Additional vitamin B supplementation should only be considered if there is a specific condition that warrants additional intake or as directed by a doctor.
